Impact of Fiber Bragg Grating as Dispersion Compensator On the Receiver Characteristics
Among the promising advancements towards cost-effective long-haul transmission is the use of Fiber Bragg Gratings (FBGs) as the dispersion compensating module (DCM). In this paper we discuss the feasibility of long-haul Wavelength Division Multiplexing (WDM) optical transmission using FBGs for the dispersion compensation & the performance is analysed by comparing the results of the receivers. A 10 Gb/s Non Return To Zero (NRZ) signal is launched onto a 100 km long standard single mode fiber. Comparison of eye diagrams & Bit Error Rate (BER) show a marked improvement in the link performance due to compensation of dispersion.
